The React-based code uses d3.scaleBand and d3.scaleLinear for positioning, while d3.csv loads the data from a remote GitHub repository. SVG rectangles render each bar, with tick lines and axis labels styled in blue and green, and tooltips reveal precise population values on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3766067d533849f58945d05342a62fbf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
